SPECIFICATION forming part of Letters Patent No. 542,492, dated July 9,1 895. Application filed I'ehrnary 18, 1895. Serial No. 538,745. (Nomodel.)

To all whom it may concern:

Be it known that I, THOMAS A. PERKINS, of Ansonia, in the county of NewHaven and State of Connecticut, have invented a new Improvement inMachines for Setting Lacing- Studs; and I do herebydeclare thefollowing, when taken in connection with the accompanying drawings andthe letters of reference marked thereon, to be a full, clear, and exactdescription of the same, and which said drawings constitute part of thisspecification, and represent, in-

My invention relates to an improved machine for setting lacing-studs,the object beingto produce a simple, compact, and durable machine,composed of few parts, adapted to be operated conveniently, not liableto derangement, and having a large capacity for work.

With these ends in view my invention consists in a machine havingcertain details of construction and combinations of parts, as will behereinafter described, and pointed out in the claims.

In carrying out my invention I employ a .As shown, it is held in anydesired position of adjustment by means of two set-screws D and Dhorizontally and vertically mounted in a vertically-arranged sleeve D asclearly shownin Fig. 2.

In addition to the vertical movement of the jaws the feeding-jaw'A isadapted to have an oscillating movement, at the outward limit of whichit receives the studs and at the inward limit of which it forces andfirmly holds the same against theholding-jaw B, which is a fixed jaw,except for vertical movement. The said jaw A has its extreme inner endshaped as at a to grip thestuds, while the inner end of the jaw B iscorrespondingly shaped, as at b. 1 The said jaw A is alsooonstructed atits inner end with a small clearance-opening A, which receives the punchD and with an undercut p0cketA which receives the heads of the studs, asseen, for instance, in Fig. 6. The jaw B is provided at the outer edgeof its inner end with a beveled centering-finger B, which is constructedand arranged to enter into the outer edge of the pocket A of thefeeding-jaw A and operates to invariably center the studs over theclearance-opening A aforesaid, whereby the studs are brought intoalignment with the punch D. The outer end of the jaw A is constructedwith a segmental shank A which is offset to the right, while the jaw Bisconstructed with a corresponding but longer segmental shank B offset tothe left and therefore clearing the shank A of the jaw A. The said jaw Ais secured by means of a screw A to a substantially circular jaw-head E,which has formed integral with its outer edge a flange E correspondingin width and thickness to the shank A of the jaw, one end of the saidshank being abutted against one end of the flange, as shown at e in Fig.11, while the opposite' end of the said flange forms anabutment-shoulder e, as shown in the same figure. The said head islocated within a circular recess F, formed in the upper end of averticallymovable carrier or block F, and mounted for oscillatingmovement upon the inner end of a large stud G, which projects into thecenter of the said recess, as shown in Fig. 9, and the outer end ofwhich is threaded for the reception of a nut G, which bears against theouter face of the block and holds the stud firmly in place therein. Thejaw B is located in the said recess F in such a manner that its lonsegmental shank B lies back of the shank A of the jaw A and the flange Eof the oscillating head E, the said shank receiving a screw B whichholds the jaw from lateral displacement and from forward endwisemovement, while an abutment-pin B located within the recess, is engagedby the extreme outer end of the segmental shank B and prevents the shankand jaw from inward longitudinal movement. The shoulder A formed in thefeeding-jaw A, adjacent to the base of the shank A thereof. engages withthe opposite face of the abutment-pin and limits the outward oscillatingmovement of the said jaw and oscillating jaw-head. At the same time theshoulder A just mentioned engages with the abutment-pin theabutment-shoulder c of the flange E of the head engages with theshoulder B formed upon the jaw 13, adjacent to the base of the shank 13thereof. 7

It will be noted that the feeding-jaw A may be readily removed from thejaw-head E, and, furthermore, that the holding-jaw B may be readilyremoved from the carrier or block F, and I would have it understood thatmy design is to supply each machine with jaws adapted to be used forsetting studs varying in size and form.

For the purpose of oscillating the jaw-head E, and hence the feeding-jawA, I provide the outer face of the head with an operating-pin E whichenters an elongated slot G longitudinally arranged in the forward end ofthe substantially-horizontal gate-lever G, which is mounted on a stud orpivot G and clearly shown in Figs. 1 and 5. Springs G and G connectedwith the machine-frame H and with the opposite ends of the lever G, holdthe same yieldingly in its normal position, in which a gate pin I,located in a recess 1', formed in the lower edge of the inner face ofthe outer end of the lever, holds back the column of studs 0, which arewaiting to be picked up one by one by the oscillating jaw A, as will bedescribed later on. The said gate-pin I is set into the open recess 1,and held in place therein by the adjacent portion of the machine-frameH, which the inner face of the lever bears against as the lever isoperated and which prevents the pin from falling out of the said recessas the lever moves up and down. The vertically-movable block or carrierF is located in a large vertical slot J, formed in the machine-frame H,and retained in the said slot by means of two correspondingvertically-arranged plates J J, secured to the machine-frame by screwsj.The said block is constructed upon its outer face with twohorizontally-arranged shoulders F F located one above the other andreceiving between them and coacting with a large cam K, secured by a nutK upon the outer end of the horizontal driving-shaft K which themachine-frame H affords a bearing for and which projects at its forwardend through a vertically-elongated clearance-slot F formed in the lowerend of the block. derstood that when this cam engages with the shoulderF it positively lifts the block, and when it engages with the shoulder Fit positively depresses the same, so that the movement of the block ispositive in either direction. The opposite end of the said shaft isfurnished with a driving-pulley K Any approved devices for feeding thestuds into the pocket A of the feeding-jaw A may be employed. As hereinshown, the machine is provided with a hopper L, into which the studs areintroduced in bulk in the usual manner. A feeding-blade L, having itsupper edge forwardly inclined, extends at its upper end into the saidhopper, in which it plays up and down through the mass of studs, thesaid blade being furnished at its lower end with an adjustable block Lsecured to it by means of a stud L and a nut L and carrying a pin Lfurnished with an antifriction-roll L", which plays in an elongated slotL formed in the outer end of the arm L of a bell-crank lever hung upon astud L and having its other arm L furnished with a long segmental slot Lreceiving a crank-pin L carrying an antifriction-roller L and mounted ina disk L, se'cu red to a short shaft L, the opposite end of whichcarries a bevel gearwheel L meshing into a pinion L mounted on thedriving-shaft K but the means just described for operatingthefeeding-blade may be widely varied without departing from my invention.As the forwardlydnclined upper edge of the blade rises through the massof studs in the hopper it picks up and lifts some of them into alignmentwith the elevated rear end of the guide-rail M, which at its said endprojects into the hopper, as shown in Fig. 2. When the blade is broughtinto alignment with the said end of the guide-rail, the studs which havebeen picked up by the blade slide forward off the same and onto the railand down the same. At its lower forward end the rail is curved andpractically brought to a bearing against the inner face of the block F,as required to bring the studs into range with the pocket A -formed inthe feed ing-jaw A when the same is at the outward limit of itsoscillating movement. A platefender. N, located above the guide-rail,prevents the studs from being derailed on their way to the oscillatingfeeding-jaw A. The column or line of studs on the guide-rail is heldback by means of the gate-pin I, before It will be un-.

ICC

mentioned, while the stud fed below the pin is prevented from escapingduring the upward movement of the block, and before it has anopportunity of entering thepocket A in the feeding-jaw, by. means of aguard O,

which is located in a vertical plane and at a right angle to the curvedlower end of the guide-rail, which it bears against.

Having fully described the construction of my improved machine, I willproceed to set forth the mode of its operation.

Lacing-studs having been fed in bulk to the hopper, the machine isstarted in operation, causing the vertical reciprocating feedblade tomove up and down through the mass of studs, of which it will catch a fewduring its upward movement and deliver them to the upper end of theinclined guide-rail, down which they will gravitate until arrested bythe gate-pin I, which we will assume to have been lifted, so as ,topermit one stud to pass below it, the said stud being prevented fromsliding off from the extreme lower end of the rail by means of thevertically-movable block F and the guard 0. Now, when the said blockis,'in the operation of the machine, depressed intoitslowest positionthe oscillating jaw-head E will be thrown to the limit of its outwardoscillation and so as to bring the pocket A of its feeding-jaw Aopposite the lower end of the guide-rail and into position to receivethe said stud, which at once glides into it. The block now begins tolift, causing the said oscillating jaw-head to be moved through themedium of the operating-pin E and the gate-lever G, which at this timeis held virtually stationary by the springs G and G Before the jaw-headin its described oscillating movement reaches the limit of its inwardmovement the beveled centering-finger B of the holding'jaw B enters theouter edge of the pocket A and engages with theouter edge of the stud,so as to drawthe same into its right position over the smallclearance-opening A of the feeding-jaw, unless the stud has alreadytaken that position under the action of gravity. The inward oscillationof the jaw-head and the inward movement of the feeding-jaw are stopped,however, before the block has completed its upward movementbytheclampingof thestud between the feeding and holding jaws and by the stopsprovidedforthepurpose. The block nowcompletes its upward movement,during which the shank of the stud is lifted against the punch D andupset. Also during the completion of the upward movement of the blockthe forward end of the gate-lever G is lifted against the tension of itssprings, whereby the gatepin is lifted above and out of contact with thelower end of the guide-rail long enough to permit another stud to passbelow it onto the extreme end of the rail, from which it is preventedfrom slipping off by the block F and gate-pin being re-engaged with theguide-rail,

.so as to prevent the column of studs thereupon. from feeding, and thegate-leverreturning to its normal position, in which it is held withsufficient rigidity to co-operate with the operating-pin to cause thejaw-head to be oscillated, and the feeding-jaw thrown outward intoposition to bringits pocket into line with the lower end of theguide-rail, from which it receives the stud last fed, and so on.

I would call particular attention to the fact that the fabric to whichthe studs are applied isheld against the punch and is not moved up anddown, whereby the machine is very convenient to operate. It will also beobserved that the machine is composed of comparatively few parts, noneof which are delicate or arranged so as to be liable to derangement.

It is obvious that in carrying out my invention the devices for feedingthe studs may be widely varied, as also may the operating connections ofthe machine. It will be clear also that the details of my improveddevices for feeding the studs to the punch may be varied. I would,therefore, have it understood that I do not limit myself to the exactconstruction shown and described, but hold myself at liberty to makesuch changes therein as fairly fall within the spirit and scope of myinvention. Thus instead of moving the feeding-jaw A and holding-jaw B upand down I might provide for the movement of the punch D toward and awayfrom the said aws.
